NW500: New Non-Mydriatic Retinal Camera Launched 

The device, which was on display at O=MEGA23 in September, now has approval from the Australian Therapeutic Goods Administration (TGA).  

It promises enhanced image quality in ambient light, even through small pupils.^1,2 

Topcon said the NW500, which has a 12-megapixel sensor, offers innovative slit scan illumination and a rolling shutter mechanism, which helps to overcome one of the known causes of poorly graded images in its ability to effectively image smaller pupils, from 2.00mm or larger.³  

NW500 “contributes to a streamlined workflow and enhanced patient experience by offering the ability to acquire retinal images in a lighted setting without the need to dilate patients”

Topcon said the NW500 “contributes to a streamlined workflow and enhanced patient experience by offering the ability to acquire retinal images in a lighted setting without the need to dilate patients”.1  

“Utilising bilateral 2-field photography, the NW500 automatically captures four images: disc centred, then macula centred (OU) to improve clinical workflow efficiencies.” 

Stereoscopic photography captures images from two slightly different positions to aid in clinical assessment. Peripheral photography can be accomplished via nine fixation points. As well, the device has touch-screen capability, and several connectivity options. 

Dr Jacon Cheng Yen Chaun, who has been using the device at Eagle Eye Centre in Singapore, said the “reduced need for dilating all patients… has certainly contributed to the smoothness of our daily operations while also making for happier technicians and patients”.
